The combination of the blue and cream vertical striped wallpaper, the dark wood wainscoting, the unique rounded wooden door with a reeded glass window marked 'M WC', and the very distinctive thick, bright yellow mirror frame is an exact match for the restrooms at the Au Cheval restaurant located in the West Loop neighborhood of Chicago. Photos from patrons on Google Maps and other review sites confirm this specific interior design.

The 'M' on the door likely stands for 'Men', indicating this selfie was taken in the women's restroom, facing the men's room door. This is the location of Au Cheval in New York City.

While the primary evidence points strongly to the Chicago location, it's plausible that another branch could have similar design elements. However, publicly available photos of the NYC location's restroom show a different design (e.g., subway tiles instead of striped wallpaper), making this a much less likely candidate unless there has been a recent unphotographed renovation or there is another restroom with this design.

The term 'WC' (Water Closet) is very common in the United Kingdom. The vintage, bespoke interior design style is also prevalent in many trendy restaurants and bars in areas of London like Soho or Shoreditch.

While there is no specific match, the general visual cues make a high-end establishment in London a plausible, though speculative, alternative.
